CTEK Lithium and Lead-Acid Smart Battery Charger / Tender

The CTEK MUS 4.3 TEST & CHARGE is an advanced, microprocessor-controlled battery charger that provides an all-encompassing solution for testing, charging, and maintaining your vehicle's battery. Starting in 2027, every C8 Corvette will be equipped with a lithium battery, and GM official training documents state that a charger is a necessity if the car sits for more than a week. This charger is your ultimate defense against dead batteries and premature wear during periods of inactivity.

Designed for safe and simple "connect and forget" operation, this unit recovers, charges, and maintains both lead-acid and lithium-ion batteries to maximize their lifespan. Prioritizing vehicle and user safety, it delivers exceptionally clean voltage with zero surges or spikes and features spark-free, reverse-polarity protection so you never have to disconnect the battery from your vehicle to charge it.

Features

  • Broad Compatibility: Supports all lead-acid (WET, MF, Ca/Ca, AGM, EFB, GEL) and lithium-ion (LiFePO₄) batteries ranging from 1.2Ah up to 110Ah.
  • Unique 8-Step Charging: Patented system automatically assesses battery condition, then revives, charges, and maintains for maximum performance.
  • Comprehensive Diagnostics: Three straightforward test programs evaluate battery voltage, starting power, and alternator health.
  • RECOND Mode: Specialized reconditioning function safely recovers deeply discharged and stratified batteries.
  • Long-Term Upkeep: Patented FLOAT/PULSE maintenance modes ensure ideal battery care during off-season storage.
  • Automotive Safety: Delivers clean power with no surges or spikes, protecting your vehicle's sensitive electronics.
  • User Protection: Spark-free operation and built-in reverse polarity protection ensure completely safe handling.
  • Hassle-Free Charging: Plug-and-play operation allows you to charge without disconnecting the battery from the vehicle.
  • Flexible Programming: Recondition and 'Snowflake' (cold weather) modes are available in both 0.8A and 4.3A settings.
